WORLD'S WORSTAIRLINE

Fly a gigantic, catastrophically cheap five-deck airliner with your friends. Serve meals, brew coffee, fight fires, re-strap runaway cargo, calm unruly passengers, and brace when the air pockets hit. Then spend the day's takings upgrading the plane. Repeat.

Play together online

Host: open the game, choose PLAY. The lobby shows a 4-letter ROOM CODE.
Friends: open the game (browser or download), choose JOIN A FRIEND and type the code with a gamepad or keyboard.
Everyone presses A on each controller to hop in. Up to 8 crew, any mix of couch, online, phones and CPU crew.

The loop

Hangar: take a free blueprint, buy equipment & aircraft upgrades.
Prep: arrange ovens, coffee machines and sprinklers, then ring the departure bell.
Fly: takeoff, then all-hands drinks, meals and clean-up rounds. The galley brews pots and heats racks (toss them up a hatch for a crewmate to catch), one of you pushes the trolley (it blocks the whole aisle!), another serves. Whoever's missed storms the emergency exit: slam it shut on them! Big fires need two extinguishers.
Payday: fares × happiness, minus lawsuits. Survive 12 days to franchise.
